» Argument Reference

The following arguments are supported:

  • name - (Required) A name for the metric filter.
  • pattern - (Required) A valid CloudWatch Logs filter pattern for extracting metric data out of ingested log events.
  • log_group_name - (Required) The name of the log group to associate the metric filter with.
  • metric_transformation - (Required) A block defining collection of information needed to define how metric data gets emitted. See below.

The metric_transformation block supports the following arguments:

  • name - (Required) The name of the CloudWatch metric to which the monitored log information should be published (e.g. ErrorCount)
  • namespace - (Required) The destination namespace of the CloudWatch metric.
  • value - (Required) What to publish to the metric. For example, if you're counting the occurrences of a particular term like "Error", the value will be "1" for each occurrence. If you're counting the bytes transferred the published value will be the value in the log event.
  • default_value - (Optional) The value to emit when a filter pattern does not match a log event.

» Attributes Reference

In addition to all arguments above, the following attributes are exported:
